Document Summary
27th feb 2018: lecture one - matter and change: physical and chemical change: Physical: property of substance can be observed without changing the substance into another substance. Chemical: substance displays only through changing its composition: phases: Gas (g): no fixed volume or shape. Attractive forces that exist between neutral molecules. Forces surrounding the hydrogen atoms (2 molecules) Where as, intramolecular forces are extremely strong bonds with the atom (one molecule: hydrogen bonding: Strong interaction that results when hydrogen bonded to a n, o, f atom of one molecule is attracted to a pair of electrons of an n, o or f atom of a nearby molecules. It is responsible for many of the structures observed for biomolecules like proteins and nucleic acids (dna: chemical change: It involved the production of a new substance. It is not easily reversible change are called reactants. The substances after a chemical reaction are called the products.
